Demag AC100-L

The Demag AC 100-L sets itself apart within the 100-ton class all-terrain crane market through a combination of long reach, superior driveability, and modern hydraulic systems. The crane rides on a 5-axle carrier with a 10x6x8 drivetrain configuration, featuring planetary reduction hubs and steering on all axles for outstanding maneuverability. Optional drive configurations such as 10x8x8 are also available to improve off-road performance. The suspension system is hydro-pneumatic and blockable on all axles, contributing to ride comfort and stability during lifts.

At the heart of the carrier is a DaimlerChrysler OM 442 LA, 8-cylinder water-cooled turbocharged diesel engine producing 370 kW (503 hp) at 2100 rpm with a torque rating of 2020 Nm at 1100–1600 rpm. This engine complies with European emissions standards and supports a 500-liter fuel tank. Power is transmitted via a ZF 16-speed automated gearbox (14 forward + 2 reverse) with longitudinal and transverse differential lockout for traction control.

The crane’s superstructure includes a DaimlerChrysler OM 904 LA engine generating 125 kW (171 hp) at 2300 rpm. It drives the variable displacement axial piston pump that allows for four independent and simultaneous crane functions. The hoist system is powered by an axial piston motor and utilizes planetary gearing with a multi-disc brake, providing smooth and precise control with built-in drum rotation indicators.

The AC 100-L’s telescopic boom is fabricated from fine-grain steel in a box-type construction, extending from 10.3 m to 50 m (33.8 ft to 164 ft). It comprises 5 sections, with the last stage operated via chain synchronization and the others via hydraulic cylinders. The boom elevation system is managed by a differential cylinder enabling an elevation range from -2° to 81°.

Cab features on the AC 100-L emphasize operator comfort and functionality. The crane cab includes a tilt function (up to 20°), sliding door, ergonomic controls, and a heater with defroster. Instrumentation includes digital readouts for hook load, angle, radius, and other lift parameters. Additional safety and automation come from the electronic safe load indicator system.

Standard counterweight options include 13.3 tons, and optional configurations are available up to 18.7 tons, with integrated hydraulic installation. The crane is equipped with numerous safety systems including hoist limit switches, pressure relief valves, analog displays, and hydro-electric servo control for boom movements.

Optional equipment enhances job flexibility with folding jibs (9.2 m or 17.0 m) at various offset angles (0°, 20°, 40°), as well as an auxiliary hoist for simultaneous dual-hook operation.

With its long boom and rugged carrier, the Demag AC 100-L is ideal for demanding lifting operations across construction sites, urban settings, and industrial installations.
